Before this bean, it was very performance intensive and complex to retrieve price after discount prices.

It is important to understand that it works by creating a temp order and out of the box, it only works by sending 1 catentry at a time, for multiple items, this bean needs to be extended.

The price is calculated as if an order is placed that includes only the current catalog entry with quantity of one. I haven't used this in a live site hence I am curious about the performance of this bean.
